What is a common ducted electrolyser? How is it different from a normal one?

Question

I am realy interested in science and it really annoys me how no-one on the internet is prepared to explain this stuff in English. Please help out. the best dictionary I have found is http://discover.edventures.com/functions/termlib.php?action=&alpha=A

but if you can think of a better one I would really appreciate it.

Often, the best way to get scientific answers is through wikipedia.   You will notice that many Yahoo answers are just cut-and-paste from wikipedia.  Either people who are too lazy to give real answers, or people too lazy to look up obvious stuff themselves.

Look up common ducted electrolysis and you get a wikipedia article on oxyhydrogen and electrolysis.  When you electrolyze water, you end up with oxygen bubbling off one electrode and hydrogen bubbling off the other.  You can duct these off separately, which is safer, because when the two gasses are mixed, they are extremely flammable.  Or, if you put them in a common duct, that just means to bubble both gasses off into the same container.  It's OK to do that if the mixed gasses go straight into an application such as a oxyhydrogen torch with a safety mechanism in place to keep the flame from backflashing into the electrolyzer (such as bubbling the gas through water before entering the torch).  But if you are going to store the gas for use later, like in a hydrogen car, you do not want to store a volatile and explosive mixture.  You would separately duct the oxygen and hydrogen and store them in different containers.
